To all whom t m ay concern.'

Be it known that I, HARRY. S. HART, a citizen of the United States,residing at Chicago, in the county of .Cook and State of Illinois, haveinvented certain new and uselful Improvements in a Convertible-CarConstruction, of which the following is a specification.

This invention constructions.- The general object of the invention is torelates to convertible car provide a car of the Hart convertible type`horizontal position to form part of the flat :door ofthe dump car, orswungfupwardly to an inclined position, in which case the doors form anextended wall of the central hopper.

In this particularaspect, therefore, the invention comprises a carhaving the stationary central longitudinal hopper portion rwith theswinging doors mounted along the upper outer edges of the hopperportion, which doors in one position form extensions of the hoppersides. ln this embodiment of the invention the hopper sides are com- 35pleted by inwardly and upwardly swinging portions which in one positionform a portion of the sides of the car.

The invention is illustrated on the accomlpanying sheets of'drawings, inwhich,--

Figure 1 is a transverse sectional view of convertible car embodying myinvention; and,

' ticularly pointed out in' the appended claims.

Referring to the figures of the drawings, it will be understood that Ihave shown a convertible'car having sides including stakes thereof',yLongitudinal. sills 12 Yare mounted over and rest upon the cross beams11.` The body of the car includes a central stationary longitudinalhopper 13 formed by an inclinedstationary side wall 14: and an iiiclinedmovable wall in the form of a door 15 whereby the load may be centerdumped. When the car is used as a flat bottom car the central hopper 13is covered. In this particular case the central hopper 13 is coveredpartially by members 16 which, when the car isarranged as a hopper car,rare used as hopper end walls spaced from the regular car end walls 17,as shown in dotted lines lin Fig. 2. The remaining portion of the hopper13 at each endis covered by a movably mounted member 26,-which when thecar is used as a hopper car is moved over upon the floor end portion 27as shown in dotted lines in Fig. 2.`

.The flat floor adjacent the central hopper 13 is formed bylongitudinally extending doors 1S which are pivotally mounted at 19along their inner edges or along the upyper outer edges of that portionof the hopper below the floorlevel. As shownat the `left hand side ofthe Fig. 1, the ioor ,door

18 is arranged in ahorizontal plane, `in

.which position it is'located when 'the car is used as a fiatbottomcar.v The door 18 in this horizontal position, normally isarrested from an upward movement by a side chord 28located along thefloor line, there being one at each side of the car acting as stops.

.In this connection it will 1oe noted thatthe doors 18, at their outerends, are Vprovided with a hinged portion 18a-which must be folded overthe door before the latter can .be elevated above a' horizontalposition.

When the car is arranged as a flat bottom c ar, the side doors 20 are ina vertical position engaging the side, stakes 10, the car `sides alsoincluding stationary portions 21 located above the doors 20. When thecaris arranged as a flat bottom car the load may be dumped tothe sidesthereof by dropping the doors 18, said doors being provided withsuitable operating mechanisin including a chain or 'cable 22 `andoperating shaft 23- carried bythe side of the car,V said cablepreferably passing through guide castings 24: carried ,by the vside walldoors 20.

When it is desired to change the car from a fiat bottom car to a centralhopper car the same is done by shifting the car side.`

doors 2OV into an inclined position, as shown at the ,right hand side ofthe Fig. 1, and in Vwhich position said slide wall doors 2O are sameinclined planetas the' other hopper portions at each sides-thereof. Itwill be understood also that the temporary hopper iioor portionsl and 26willbe moved from their full line positions shown in Fig. 2 to f theirdotted line positions shown inthe same figure. -Heretofore with thecentral `hopper arrangement no provision has been made to dump a portionof the load to theisides of the car. However, by means of my im'- proveddoor arrangement the doors 18 may be 'lowered from their inclinedposition in which they form hopper sides to positions wherein ka portion`of the load .will be dumped to the sides of the car. If desired, thecentral hopper door 15 may be opened at the same time for centerdumping. Y

It is my intention to cover all modifications falling within .the spiritand scope of the following claims.

vIclaim: Y 41. In a car ofthe classdescribed, a central longitudinallydisposed stationary hopper portion', and doors hinged along the upper Youter edges of said hopperV portion arranged to `form in one position apart of the horizontal ioor of the car and span the distance betweensaid hopper edges and the sides of the car and to be'A swung upwardlyfrom the horizontal position to form a portion of a hopper side. y Y

2. In a car of the class described, a cen-Y tral longitudinally disposedstationary hopperzportion, 'doors hinged along the upper outer'edges of'said hopper portion arranged to form in one position a part of thehori-V zontal floor of the car and span the distance between said hopperedges and the sides of the car andto be swung upwardly from thehorizontal position to form a portion of a hopper side', and inwardlyswinging; doors hinged to and forming a part of the car sides in oneposition also forming a portion ora hopper side. i g

3. In a car of the class described, a central longitudinal stationaryhopper portion, andA floor doors hinged along the upper outer edges ofsaid hopper portion arranged Ato beswung upwardly to form a portion of ahopper side, said floor doors being movable rom such position to dumpmaterial to the sidesof the car. i i

4. kIn a car of the class described, a central longitudinal stationaryhopper portion,

chords arrangedalong the side `of thecar Vat the flat floor level, ,andldoors hinged along the upper outer edges of said hopper portion arrangedto form in one position a part of the horizontal floor of the car and`to be swung upwardly from thehorizontal positionto forni a portion of ahopper side, said doors normally being prevented Vfrom moving from ahorizontal position to a position to form ajhopper side wall by vsaidchords, saidv doors being provided with hinged portions which permit thedoors to Vbe moved vupwardly beyond said chords.V

5. In a car of the class described, al central longitudinally disposedstationary hopper portion, chords arranged at the sides of the car alongVthe Hoor line thereof, 'and doors hinged along theupper outer edges ofsaid hopper portion arranged to take an inclinedposition to form ahopper side wall and to take a horizontal position orforming a portionof the floor, said doors having upwardly folding hinged portions! whichnormally engage the said chordsy to prevent upward movement of the doorsbeyond a vhorizontal position, said hinged portions being movable into apositionto permit Vmovement upwardly beyond said chords.

longitudinally disposed stationary hopper portion, doors hinged alongthe upper outer edgesy ofV said ,hopper portion arranged to form in oneposition a part of the horizontal ioor of the car and to be swungupwardly from the horizontal position to form a portion of a hopperside, lsidey wall doors movable into a position to form hopper sideportions, and means including a flexible member for supporting the floordoors and side wall doors inthe .positions in which theyform hopper sideportions.

' 8. A vcar of the class described including a body having a side walldoor and a licor door which may be moved into an inclined position toform ahopper side wall, one of said doors being supported by the otherin said position, andthe floor door being movable from said inclinedAposition for side dumping. v

Y 9. A car of the classl described including a body having a side walldoor and a floor door which maybe moved into all inclined position toform a hopper side Wall, means for supporting the side Wall door ininclined position, and means associated with said side Wall door forsupporting the lioor door in Said inclined position, the Hoor door beingmovable from said inclined position for side dumping.

10. A car .of the class described including a body havingmovable sideportions and movable floor portions Which respectively occupy verticaland horizontal positions when the car is arranged as a Hat bottom carand Which take an inclined position to form a hopper side Wall when thecar is arranged as a hopper car, means for supporting the movable sideportion in inclined position, and means associated With said side Walldoor for supporting the movable floor portion in said inclined position,and said floor portion being movable for side dumping from an inclinedhopper position and from a horizontal position.
